Darn tough requires you to return them on your dime, although some retailers like REI will allow you to exchange on site. Cloudline is another great brand to consider that offers a true hassle free lifetime warranty. Fill out an the online form and wait for your replacements (no returning). They are US made and they offer discounts to military, teachers, and more. They send me 20-25% off discounts via email frequently as well.

Second the purple mattress. We are going on 4 years and wouldn't hesitate to buy another. Previously owned a temperpedic cloud series mattress.

I had a similar problem and found Parachute Pillows:

While they arent cheap, they give you 60 days to return it if you aren't satisfied.

No pillow is BIFL, but this one is made very well and very comfortable. I will be buying another when the time comes. Good luck with the search!!

Love my cloudline socks. Did the same as OP and tried a few and settled with them as they were most comfortable for my feet.

Had a similar problem, went with cloudline socks. Also have a hassle free lifetime warranty like the OP

Get a small squirt bottle of ISO alcohol and spray the base and inside the head after using - will prevent build-up and keep looking clean.

Look into cloudline socks, they have a true hassle free lifetime warranty that doesn't require mailing them back. Darn tough is a solid brand, but the warranty and alternate styles of cloudline are what sold me in the end.

Second cloudline - quality socks with a true hassle free lifetime warranty.

Second cloudline socks - their warranty is truly hassle free and they have various styles for various activities and looks. Darn tough warranty was a bit of a pain and the sales weren't as frequent as cloudline. Point 6 is another brand, however they fit a bit tight for my liking. Best of luck with the search!
